The welding machine is easy to adjust and control. The operator can easily adjust the welding parameters. There is an automatic start/stop button on the panel, which is convenient to start and stop of the equipment.
Our switch welding machine has a high degree of automation and easy adjustment, which greatly reduces the labor intensity of welding workers and improves the overall production efficiency. The quality of steel pipe welding is also guaranteed. In addition, its environmental protection, energy saving and noise reduction performance is also remarkable.
What are advantages of high efficiency switch welder
1. High efficiency
High efficiency switch welder is a highly efficient welder that delivers high-quality welds at a rapid rate. This welding equipment is equipped with state-of-the-art technology that ensures optimal performance and productivity.
2. Versatility
High efficiency switch welder is capable of welding a wide range of materials, including steel, aluminum, brass, and copper. This versatility makes it an ideal choice for businesses that need to work with different materials.
3. Easy to use
High efficiency switch welder is very user-friendly and easy to operate. Its intuitive interface and simple controls make it easy for both beginners and seasoned welders to use.
4.Energy-efficient
High efficiency switch welder is designed to be energy-efficient, which means that it consumes less power compared to other welding machines. This not only saves energy costs but also helps to reduce carbon emissions.
5.Less installation cost
For example 100kw solid state welder, the traditional welder installation cost is around USD800(purchasing cable, nozzles, cable bridge and brackets), moreover, welder room or elevated platform is necessary, all the cost will be about USD800-1600.
6.Small harmonic interference, no pollution to the power grid
Three-phase AC power supply coverts the alternating current to the direct current through the full-bridge rectifier circuit. The line is equipped with a number of well-matched filter networks, leading to a very few harmonic components during operation of the high-efficiency switch welder (all-in-one machine). The power factor may reach 0.96 or more.

How to maintain a high-efficiency switch welder？
On solid-state welders, the circuit design, lower voltages, and circuit-board-mounted technology help to increase reliability and mill uptime. When problems do arise, however, fault diagnostics may be needed.
Most solid-state welders today are delivered with a computer graphics diagnostic package. If a fault occurs, the diagnostics package directs operators to the most probable cause. A modem can also be installed to access the system remotely to aid in troubleshooting.
With any welder, the most common fault is a short circuit, caused by an insulation breakdown or component failure.
When a fault does register, the diagnostics should aid in directing operators to the first area to investigate, which is usually outside the welder proper and in the area of the coil or contacts:
1.Inspect induction coil for overall condition and insulation status; also check coil connections to bus bars.
2.Inspect contacts for excessive wear; check insulation between contacts.
3.Inspect bus bar insulation for contamination from the mill area; it should be clean and free of holes or tears.
4.Inspect the weld area, the weld rolls, the impede, and general alignment of the coil or contacts for any mechanical interference.
5.If no fault is found in the external area, inspect the power supply and inverter cabinet. Look for the obvious — a water leak, or condensation buildup, or any general overheating.
6.If no problem is found, review the fault array. Most solid-state welders have an internal diagnostic array that will show whether or not levels of the system are functional. This is usually LED-driven and mounted on the assemblies.
7.In the inverter section, first inspect the fault LED array for proper illumination: HF modules, HF power supplies, auxiliary supplies, and HF control circuitry.
8.If all the inverter LED are normal, inspect the power supply fault array: the SCR assembly, control board, firing board, and 24-volt power supply.
The solid-state high-frequency welding machine consists of a rectifier cabinet, an inverter, an output cabinet, a closed-loop water cooling system, a central operating console, and a mechanical adjustment device.
1. Switch Rectifying Cabinet
The switch gear and the rectifier are integrated here into one switch rectifying cabinet, which enables both the switch gear function, and the rectifying control function of the solid state high frequency welder.Incoming MCCB (molded case circuit breaker), incoming current meter, incoming voltage meter (switchable type), and incoming voltage indicator.3-phase fully-controlled thyristor rectifier bridge enables power regulation.Smoothing reactor, smoothing capacitors and filter to increase the smoothing coefficient.
2. Inverter Output Cabinet
The inverter circuit consists of MOSFET single- phase inverter bridges connected in parallel, with the power of each bridge designed as 120kW/60kW. Thus the power is accumulated in the style of building blocks. Each inverter board is designed into the drawer structure with slides on both sides, which facilitates installation and repair.The powers is combined through several transformers (called matching transformers) and by direct resonance between the tank circuit resonant capacitors (low voltage) and the inductor, it is transferred to the welding unit-via the bus lead, and no welding transformer is needed here.Sealed cabinet with the air conditioner installed on the top of it.
3. Central Operator Console
The central operator console allows remote operation and power regulation of the welder. It is equipped with HMI (human/machine interface), indicates DC voltage and DC current of the H. F. welder, and armature voltage and field voltage of the motors of the forming and sizing mill. Design of the central operator console is customized according to different types and quantities of the motors. The power-speed closed loop control /automatic power-speed control function is optional.
4. Mechanical Adjustment Device
2-D mechanical adjustment device: applicable for solid state induction welders only. The inverter output cabinet is installed on the adjustment device, so the position of the inductor can be manually adjusted.3-D mechanical adjustment device: applicable for both solid state induction welders and solid state contact type welders. The inverter output cabinet is installed on the adjustment device, so the position of the inductor can be adjusted manually or electrically.
5. Closed Loop water cooling system
The GPKL-II cooling system adopts a closed cooling tower, in which the blowers and water spraying hoses on the top will cool the soft water already pumped into the finned tubes. The spraying water (normally purified tap water) is accumulated at the bottom of the cooling tower. It is pumped into the spraying hoses and sprays onto the surface of finned tubes-Part of the spraying water will vaporize when it is falling, thus carries away some .heat and partially lower the temperature of the soft water circulating inside. The vapor goes up due to the blower and intensifies the cooling effect when it passes the finned tubes again, and finally goes out of the cooling tower. The other part will fall through the PVC heat exchange layer which is located under the two blowers and above the finned tubes, thus gets cooled by the cold air passing by and finally joins the spraying water at the bottom.
